Plot hole: Any invisible man would be blind. This is because if your retina in the eye is as transparent as an invisible man's, any image that can form on it will pass right thorough it without generating any vision signal via optic nerve. Thus your brain gets no visual signal if you are invisible.
Continuity mistake: About two thirds of the way through Ch. 1, Sookie serves a pitcher of beer to her brother Jason's boss, Shirley Hunter. But in the previous book, Dead to the World, Jason's boss Shirley's last name was Hennessey (Ch. 3).
Factual error: When the Australian astronaut is describing the Battle of Dehli, he says "Just like the limeys used to do in the colonial days." Limeys is just an American term. In Australia, Englishmen are referred to as pommies.
Other mistake: E-mails between Salander and Blomvkist on pages 311 and 312 (2009 MacLehose Press hardback) are repeated word for word on pages 370, 371.
Plot hole: It took Ender only a few hours to unravel a mystery that 3 generations of highly educated and skilled xenologists and xenobiologists were unable to do. Pipo, of the first generation, was restricted by the rules imposed on him by the congress and he found out the truth but died because of it. After that Libo should have simply asked the piggies what happened and should have digged into the piggies' reproduction system, like he should have done in the first place as that is his job. Both Libo and Miro and Ouanda broke the rules so they shouldn't have had a problem with asking the right questions. They weren't afraid of the piggies either, loved them even. Libo would have had the answer to the reason for the death of his father and understood the piggies in a week, even though Novinha had hid the original data. If not him Miro and Ouanda would have had plenty of time to figure it out as well, just by asking questions. They would have learned a lot more about the descolada virus decades sooner as well, giving them more chance to combat it successfully.
Suggested correction: This entry first claims that it took three generations to find the solution, then states that individual in the first generation found it. If one xenologist can arrive at the solution from scratch, a literal genius like Ender can certainly rapidly come to the same conclusion using the data the next two generations compiled in the meantime.
They were all geniuses. The other 2 generations should have found out just a quickly or even quicker if they would have just simply done their jobs. It doesn't make sense.
But in Xenocide Miro's siblings like Ela, Olhado, Quarra and Grego are in the same league as Ender in intelligence, solving impossible questions without either Ender or Valentine even grasping it well enough to understand. Surely Miro isn't the only one lacking. They got that genius from their parents, the second generation xenologists Libo and Novinha who are both geniuses as well. At least the third generation should have figured it out long before Ender showed up. Mostly my point is they haven't actually done their job in all this time instead of them not being as smart as Ender to figure it out. Just ask the right questions like Ender did and voila. Its their job to ask questions but they didn't do it and their attitude towards the piggies is all wrong.
Other mistake: On page 30, the book says, "Have you ever wanted to see Iris' Dragonite beside the spunky Pikachu?" despite Dragonite not appearing. This likely because this part of the caption on this page was copied directly from the previous book.
Continuity mistake: When Aravis and the Horses are at the Hermit's and Shasta is at Anvard, the three decide it is time to resume their journey to Narnia. Aravis says, "We must see Shasta first and say good-bye to him - and - and apologize." At this point they do know he is the king of Archenland's son and will be staying in Anvard. That is revealed later to them in the chapter. She should have said, "We need to go to Anvard and get Shasta and then go to Narnia."
Other mistake: On page 178, Striaton Gym is misspelt as "Straiton Gym."
Continuity mistake: David and Steve are playing racquetball. There is nothing on the brown wooden floor, and neither have a towel. David becomes woozy, so Steve checks on him. There is a white towel on the floor, behind their feet, which disappears when they resume their game. (00:01:42 - 00:02:20)
Plot hole: In the 8th Wizard Of Oz book titled Tik-Tok Of Oz, the group runs into Polychrome, the rainbow's daughter. Polychrome and Shaggy Man first met up in book #5 titled The Road To Oz. However in this book, Shaggy Man and Polychrome act as if it is the 1st time they ever met each other. They make no mention of them meeting before in the prior book.
Other mistake: In the picture of Twig's woodtroll village (Corgi edition page 291), it shows the village with a large tree cabin in the middle. At the bottom of this tree, you can see Twig and Cowlquape standing with a small figure that is probably an oakelf. We can assume this oakelf is Spooler because the only other oakelf is Taghair, who is in his caternest. If the figure is Spooler then this is a definite mistake because Spooler died in the last chapter. Twig and Cowlquape should be standing with Goom the banderbear.
Continuity mistake: In previous books (such as The Face of a Stranger), Hester Latterly's sister-in-law is called Imogen. In Chapter 7 of this book, however, her name is given as Josephine.
Other mistake: On page 170, when Quentin is at breakfast and Poppy joins them and we learn she's from Australia the text reads "if that was true he could why see Poppy had gotten the hell out." It should say "see why."
Continuity mistake: In the first book, A Wicked Slice, Graham Sheldon was either 30 (beginning of Ch.2) or 31 (end of Ch.7). Now, in this fourth book, it is two years later, and Graham is "now at the age of twenty-nine" (middle of Ch. 1). He is getting younger.
Factual error: In chapter 8, Barbara is thinking about bullfighting, and how she had seen the horses being disembowelled by the bulls. But Barbara didn't arrive in Spain until 1936, and since 1928 horses used in bullfighting have been legally required to wear protective padding that prevents them from being injured by the horns (so the horses can be reused in other corridas).
Continuity mistake: In section 12 of chapter 11, Henry thinks about how "He, Pete, Beaver and Jonesy's wife had kept a secret among them", that Jonesy's "heart had stopped twice" after he was hit by a car about 10 months earlier. This is a mistake because earlier that day, in section 8 of chapter 3, Pete hadn't known about it - Henry tells Pete that Jonesy's "heart stopped in the ambulance", and Pete is shocked to hear it.
Factual error: Britons will be grateful to know that it would be impossible for the UN to order the nuclear destruction of Great Britain. The UK, being a member of the Permanent Security Council has the power to veto any UN decision.
Plot hole: It is revealed in the book that Melancholia's reflection is killed instead of Melancholia to cover their tracks. But reflections are frequently described in the book to be able to be spotted by sorcerers "a mile off." And yet not one Sanctuary Agent or the cleanup crew notice and alert the Sanctuary or Skulduggery.
Factual error: During Soneji's trial in part four, the prosecuting attorney objects when the defense asks Cross a leading question. Since Cross was called by the defense as a hostile witness, it is legally permitted to ask him leading questions.
Continuity mistake: In The Bridal Dance and And About Time Too, Will checks himself in the mirror, although later it says he can't afford one.
